Zoom to custom extent - PHP

[Kevin Grootendorst]

Bill,
OK, now we're getting somewhere.  I included the following before the if
statement:
echo '<pre>';
print_r ($http_form_vars);
echo '</pre>';

On a normal page load, the following is returned:

Array
(
    [0] =>
)


When I select the 'QuickZoom' feature, I receive the following:

Array
(
    [WMSlayers] => 1
    [layer_status] => Array
        (
            [0] => New York Counties
            [1] => Ontario Municipalities
        )

    [ViewRegion] => 7200000,833270,7291840,894520
    [PrevStateKey] =>
BBOX=7121000,814428.33333333,7600000,1133571.6666667|SRS=init%3Depsg%
3A50000|MAPSIZE=600,400|LAYERS=0,1
    [NotFirstLoad] => 1
    [RosaMode] => 1
    [ROSA_CMD] =>
    [INPUT_TYPE] =>
    [INPUT_COORD] =>
    [QueryString] =>
    [doQuickZoom] => 1
)

Note that the page just refreshes with the current extents.  It did not
zoom to the municipality I selected.  However, the $adExtents[n] variables
are being set to the right extents.
